IMPROVEMENT IN noon-noms.

. The Schedule referred to in these Letters Patnt and making part of thelame. y

To all 'whom it may concern:

Be it known that I, ALMON' F. WARREN, of Brooklyn, in the county ofKings, and `State of New York have invented a new and useful Improvementin Bolts for Doors, Windows, Shutters, 85o.; andi do hereby declare thatthe following is a full, clear, and exact description of the same,reference being had to the accompanying drawings, forming a part of thisspecification, and in .which- Figure l represents a longitudinalsectionof a bolt constructed according to my improvement, and

Figure 2, a trausversesection of the same.

Similar letters of reference indicate corresponding parts in both gures.

This improved bolt is especially designed for use Vupon the doors ofstate-rooms of steambOatS, and

other'doors liable to a shaking or jarring action, but

is also applicable to other doors, as w'ell as to shutters and windows.

The object of the invention is to obviate the rattling of the bolt inits socket, and otherwise to provide a neater and better bolt than isnow used for said purpose.

The invention consists in the combination, with the tubular socket of asliding bolt, of an elastic sleeve, which always fits snugly to theexterior of the socket, and so prevents the bolt from rattling. l

Topenable others to make and use my invention, I will proceed todescribe it, with reference to the drawings. l

A is a cylindrical bolt of the ordinary construction," fitted to slidewithin a tubular socket, B.

Said tubular socket B is constructed of sheet-metal, preferably of onepiece, but may be constructed in. other ways.

When thus constructed of one piece of sheet-metal, said piece is curvedor bent longitudinally 'down 'its centre into a tubular form, or nearlyso, and its outer portions or'edges bgrlt or doubled back, so as to formflanges' f f, for fitting against a flat surface, and of suicientbreadth for reception of screws, thereby forming a tubular socket,whos'e transverse sectional form is shown at fig. 2.

C is an elastic sleeve, constructed also of sheetmeta-l, and tted toslide over the socket longitudinally, and is connected, through thesocket, tothe bolt A, by means of the shank gf the knob, which passesthrough a slot cut lengthwise of the socket, and is screwed or otherwisesecured in the bolt, so that by the sliding of the sleeve over thesocket and the shank of the knob within the slot, longitudinal movementis impart-edtov said bolt.

Said sleeve does not form a complete circle in its transverse section,as may be seen by reference-to'fig.

2, but is left open at its under side, so as `to allow for its beingpassed over the tubular portion of the socket,

and before it is placed upon the socket, it is sligl'ltly smaller thanis required for an exact fit, so that after having been forced thereonby expansion, it will clasp or hug the said tubular portion of thesocket, thereby preventing all rattling of the parts.

It is preferred to have the elastic sleeve O of sufficient length to.cover the longitudinal slot in the socket, whether the bolt A be pushedin or out, so as Vto exclude dust and other foreign matter from theinterior of the socket.
